DCS302 DUAL CYLINDER SCALE INSTALLATION & OPERATION MANUAL Eagle Microsystems, Inc. 366 Circle of Progress Pottstown, PA 19464 www.eaglemicrosystems.
DCS302 GENERAL INFORMATION GENERAL The DCS302 is a dual cylinder scale designed specifically for the water and wastewater industry. The scale base and weighing surfaces are made of Type 2 PVC plastic and are guaranteed for five years against environmental damage. All mechanical parts, wherever possible, are made of stainless steel or protected with a durable chemical-resistant powder finish. The DCS302 can accommodate any cylinder that does not exceed 12” diameter and 150 lbs. net weight.
INSTRUCTIONS DCS302 DUAL CYLINDER LOAD CELL SCALE 1. Before placing scale in operation remove the six (6) plastic stops and the aluminum shipping plate located on the underside of the scale. 2. Determine service location of scale and position base 2 1/2-inches or more from the wall. 3. Anchor scale base securely to smooth, level floor using 3/8-inch anchor bolts (not supplied) through the four (4) 1/2-inch diameter holes in the corners of the scale base.

TEST PROCEDURES DCS302 DUAL CYLINDER LOAD CELL SCALE 1. After assembly a known weight of 250 lbs. is alternately placed on each platform and removed two times in order to flex the components of the scale base. 2. Upon loading the scale for the third time, the display of the EI-2000 indicator allowed to stabilize. The display value is noted and, in Mode 3 Automatic Operation, the display is adjusted to read the known weight using the Up/Down arrow keys.
